Symptoms of thrush in an adult may include: 1  A burning feeling in the mouth and throat (at the start of a thrush infection). 2  White patches that stick to the mouth and tongue. 3  A bad taste in the mouth or difficulty tasting foods.
The most common causes of oral thrush in adults are the use of steroid inhalers (preventer inhalers) and the use of dentures; other possible causes are a previous course of antibiotics, diabetes, malnutrition, or a compromise of the immune system by some other factor, in which case the doctor should be consulted.
